Great movie. Let me just c&p my thoughts in from elsewhere:
Well it's certainly different, and in reference to what (guy on another forum) said earlier it does feel quite removed from previous Bonds, and I think the hardcore fans which have loved Bond for what it is known for (cheesy lines and OTT gadgets) may find it hard to like this. But after the dire past two Bond's, this movie gave the series what it needed, a good kick up the arse.
Bond had emotion, felt real, and the whole thing felt believable.
Enjoyable, and yes the Martini line was ace.
